In the words of the authors, the paper by A. W. Bauer et al., from the University of Washington in Seattle, on a standardized single-disk method for antibiotic susceptibility testing “. . . consolidate(s) and update(s) previous descriptions of the method and provide(s) a concise outline for its performance and interpretation.” Clinical microbiologists were relieved that finally a disk diffusion...

A new series of semisynthetic, water-soluble pneumocandin analogs has been found to be extremely potent against Pneumocystis carinii in an immunocompromised-rat model. These compounds are 5 to 10 times more potent than the parent natural product, pneumocandin B0 (L-688,786) (R. E. Schwartz et al., J. Antibiot. 45:1853-1866, 1992), and > 100 times more potent than cilofungin. One compound in par...

Neplanocin A, a novel cyclopentenyl analog of adenosine, is a naturally occurring antibiotic which exhibits significant antitumor activity against L12 10 leukemia in mice (Yaginuma, S. , Muto, N., Tsujino, M., Sudate, Y., Hayashi, M., and Otani, M. (1981) J. Antibiot. 34, 359-366). In the present study we demonstrate that neplanocin A is also a potent inhibitor of S-adenosylhomocysteine (AdoHcy...

conclusions the result of the current study showed the growing number of nosocomial infections associated with xdr a. baumannii causing difficulties in antibiotic therapy. resistant strains increasingly cause public health problems; therefore, their early detection is essential for healthcare centers. results among the 121 isolated a. baumannii, 44% and 56% were isolated from female and male, r...

this laboratory study simultaneously was conducted to evaluate the resistance to heavy metals, silver, cadmium and a number of commonly used antibiotics. sampling was done in 2014 of the two silver workshops in isfahan, and the inlet of phase 2 of shahin shahr wastewater treatment plant, isfahan. to isolate resistant bacteria to metal silver and cadmium and review multiple resistance to other m...

improving cleaning and disinfection performance must be taken into account for prevention and control of infection. health care settings are engaged in a battle against healthcare associated infection (hais). the importance of infection prevention and control is increasing due to rapidly developing strains of multi-drug resistant organisms (mdros) that can result in serious illness and even dea...

We report here on the characterization of a vancomycin-resistant Enterococcus faecalis (VREF) isolated from a dog with mastitis. The isolate was positive for the vanA, ermB, and tet(M) genes, with vanA and ermB carried on the same transferable plasmid. Comparison of this isolate with VREF from poultry and human sources in New Zealand demonstrated identical SmaI macrorestriction patterns and Tn1...
